NONHEAT CONDUCTING RECEPTACLE.

Application filed May 3,

To all whom it may concern.'

Be it known that I, GEORGE J. WALZ, citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented new and useful Improvements in Nonheat Conducting Receptacles, of-which the following is a specification.

This invention relates to new and useful improvements in receptacles and more particularly to a non-heat conducting receptacle, the main object of the present invention being the provision of a receptacle of this type which is particularly adapted for use for containing valuable papers in order to protect them against loss by fire.

Another object of the present invention is the provision of a receptacle of this type wherein the construction of the same is so carried out as to reduce to the minimum the cost of such types of receptacles and, at the same time, prevent fire from reaching the contents of the same.

A further object of the invention is the provision of a receptacle of this type, the construction of which is nearly all of fireproof material and the walls thereof provided with suitable spaces forming dead air cells which will eliminate to a minimum the possibility of heat reaching the contents of the receptacle.

With the above and other objects in View, the invention consists in the novel features of construction, the combination and arrangement of parts as hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings, in which:

Figure 1 is the perspective view of a receptacle constructed in accordance with my invention.

Figure 2 is a longitudinal sectional view, taken on the line 2-2 of Figure 1.

Figure 3 is a transverse sectional view, taken on the line 3 3 of Figure 1.

Figure 4 is a detailed longitudinal section, showing the inner cell partly removed.

Figure 5 is a side elevation of the inner cell, parts of the same being broken away and illustrated in cross-section.

Figure 6 is a side'elevation of the corrugated member, parts of the same being broken away and illustrated in section, and

Figure 7 is a side elevation of the inter- 1924. Serial No. 710,939.

mediate chamber, parts of the same being broken away and illustrated in section.

Referring now more particularly to the drawings, the numeral 1 indicates the xouter main body cell of my improved receptacle, one end of which is closed, as shown at 2, and this body is provided within its side walls at a point adjacent the closed end wall 2 with a beading 3, which forms upon the interior of the body a recess 4. The removable cover portion 5 which corresponds in shape to the main body 1 is also provided with a closed end portion 6 and further provided adjacent the closed end 6 with a beading 7 which forms the recess 8 upon the interior of the cover.

Arranged within the body member 1 and lying against the inner face of the closed end 2 is a layer of tireproof material 9 and arranged in spaced relation with this layer 9 is a second layer 10, the edges of which are disposed within the recess 3 in order to retain this second layer 10 in position. Arranged within the space between the layers 9 and 1() is a layer of corrugated ireproof material as indicated at 11, the channels in the corrugated material forming suitable dead air spaces between the inner layer 10 and the closed end of the body 1, thus preventing heat from entering the interior of the body.

The closed end portion 6 of the cover 5 is constructed in the same manner as the closed end portion of the body 1 and includes the outer ireproof layer 9, the inner layer 10 and the corrugated layer 11.

Arranged within the body 1 and fitting closely to the inner face of the walls thereof is a fireproof enclosure 12, said enclosure being of the same general shape as the outer body 1 and cover 5, and of suitable length so that the ends thereof will abut the inner layers 10 in each end of the main receptacle, or in other words, the layers 10 will be tightly tted against the ends of this enclosure when the cover 5 is in position for closing the receptacle, as illustrated in Figure 1.

Arranged within the enclosure 12 is a layer of corrugated iirproof material as indicated at 13. This inner receptacle or layer of material 13 is formed in the same shape as the body 1 and is of the same length as the enclosure 12 so that the ends thereof will fit tightly against the inner layers 10 of the body 1 and cover 5 when the cover is in a closed position.

The inner compartment of the receptacle is formed of a layer of fire roof material as at 14, of the same general s ape as the other members forming the receptacle and fits snugly within the corrugated layer 13, the inner compartment 14 being of the same length as the corrugated member 13, so that the ends thereof abut the inner layers 10 when the cover is in a closed position.

From the above, it will be noted that when the several layers or compartments 12, 13 and 14 are arranged in position within the receptacle 1, the channels of the corrugated layer 13 will form suitable dead air cells between the enclosure 12 and the compartment 14 so as to reduce to a minimum the chances of any heat reaching the inner compartment. In assembling thedevice, it is preferred to have the enclosure 12 secured to the inner walls of the body 1 by any suitable type of adhesive and the corrugated layer 13 and inner compartment 14 may also be secured together and to the enclosure 12 by any suitable form of adhesive, particularly of a type which is ireproof so that any movement on the part of either the enclosure, the corrugated layer 13, or compartment 14, with respect to the body 1 will be prohibited. The cover 5, however, is removable from the outer end of the chamber formed by the layers 12, 13 and 14, thus leaving one end of the receptacle open when it is desired to place papers or the like therein. It will be readily understood that any suitable means may be provided for retaining the cover 5 in a closed position with respect to the body 1,

althouh it is preferred to have the cover 5 fitting snugly over the outer enclosure 12 to prevent removal thereof.

From the foregoing, it will be apparent that I have provided an extremely simple and durable device of this character and one which can be manufactured and placed upon the market at a relatively small cost and wherein the construction of the same is such as to reduce to a minimum the chances of heat entering the inner compartment of the receptacle.

While I have shown and described the preferred form of my invention, I wish it to be understood that various changes and alterations can be made without departing from the spirit of the invention or the scope of the appended claim.

I-Iaving thus described my invention, what I claim is:

A receptacle of the character described including an outer body casing, a cover shutting the open end of the body, the closed end of said body having recesses in its walls upon the interior thereof, a separable layer of iireproof material lying adjacent the closed end, a corrugated layer of material lying on the iireproof layer and a second layer overlying the corrugated layer with its edges in said rec-esess to retain said layers in position and a plurality of layers of iireproof material arranged within the body, of the same general shape as the body and of a length equal to the combined length of the body and cover.

In testimony whereof I affix my signature.

GEORGE J. VVALZ.
